Overview of (DVT)

Deep Vein Thrombosis (DVT) is a condition where a blood clot is also known as a thrombus which forms in a deep vein usually in the lower limbs although it can occur in other parts of the body. DVT can lead to serious complications if not treated immediately such as a pulmonary embolism (PE) which occurs when a clot breaks loose and travels to the lungs.

Types of (DVT)

1. Proximal DVT: A clot that forms in the deep veins of the thigh or pelvis. This is more dangerous as it has a higher risk of causing a pulmonary embolism.

2. Distal DVT: A clot that forms in the calf veins. While less likely to cause severe complications it still requires medical attention.

Symptoms of (DVT)

Swelling and pain especially when standing or walking.

Skin discoloration and warmth around the affected area.

You may feel heaviness, cramping or tightness in the leg.

Not always noticeable so stay aware of unusual leg symptoms.

Causes of (DVT)

Long periods of immobility for example long flights, bed rest after surgery.

Injuries or vein damage from surgery or trauma.

Health conditions like cancer, heart disease or hormonal changes for example pregnancy and birth control.

Family history of clotting disorders or previous DVT.

Complications in (DVT)

• Pulmonary embolism: Clots can travel to the lungs, causing chest pain, shortness of breath or even death.
• Post thrombotic syndrome: Persistent leg pain, swelling and skin changes after a clot.
• Long term venous insufficiency: Damage to veins may result in chronic leg swelling and discomfort.

Risk Factors of (DVT)

• Age: The risk of DVT increases as you age particularly after 60 years.
• Immobility: Sitting or lying down for long periods such as during long flights, extended hospital stays, or after surgery, can slow blood flow and promote clotting.
• Obesity: Being overweight puts extra pressure on your veins, making it harder for blood to flow freely, increasing the risk of DVT.
• Smoking: Smoking damages blood vessels and increases the likelihood of clot formation putting you at higher risk for DVT.
• Pregnancy: Pregnancy increases pressure on the veins in the pelvic area and alters blood clotting raising the chances of DVT.
• Hormonal changes: Using hormonal birth control or hormone replacement therapy can increase clotting risk especially for women over 35 who smoke.
• Family history: If close family members have had DVT you may be more likely to develop it yourself, as genetic factors can play a role.
• Previous DVT or PE: Once you have had DVT or a pulmonary embolism (PE), your risk of recurrence increases.
• Chronic medical conditions: Conditions like cancer, heart disease and inflammatory bowel disease can raise the risk of DVT.
• Long-term sitting or standing: People with jobs that require sitting for hours or standing for long periods are more susceptible to DVT.

Preventions of (DVT)

• Stay active: Move regularly to promote blood flow especially during long periods of sitting.
• Wear compression stockings: These help reduce swelling and improve circulation.
• Stay hydrated: Drinking water prevents your blood from thickening.
• Quit smoking: Smoking harms blood vessels and increases clot risk.
• Maintain a healthy weight: Reduces pressure on veins and improves circulation.
• Exercise regularly: Activities like walking or cycling boost blood flow.
• Elevate your legs: Helps improve circulation if you’re sitting for long periods.
• Follow doctor’s advice: Consider prescribed blood thinners if at high risk.
